These photos (above), from a Sellicks Foothills vineyard, show a good example of organic weed control and how mulches can improve your soil. This vineyard has been applying mulches for three seasons. The undervine area has now got a thick covering of mulch made from waste plant material and tree barks. No significant weeds grow through it only some patches of clover and other 'soft' plants.
The owners have also been adding complex organic matter (in the form of Lawrie and Co's Biologic Blend). This is to help increase the amount of soil organic matter.
